This plugin lets you move your blog from Weebly to WordPress. It crawls your Weebly blog and copies your posts on Weebly to your WordPress site. If you also need to move comments and tags (categories), use my <a href="http://codecanyon.net/item/weebly-to-wordpress-import-plugin/7751174" title="premium Weebly to WordPress migration plugin" rel="nofollow ugc">premium plugin</a>. In any case – make sure to install and run <a href="https://wordpress.org/plugins/import-external-images" title="Import External Images plugin" rel="ugc">Import External Images plugin</a> after you’re done with moving your blog data to get your images from Weebly’s server to your own.
If you’re on a restrictive shared hosting environment (such as DreamHost or BlueHost), there is a possibility the import process gets terminated and you won’t get all of your data. If this happens, try generating RSS feed for your blog using my free <a href="http://weeblyrss.appspot.com" title="Move Weebly blog to WordPress" rel="nofollow ugc">Weebly blog RSS generator web app</a> and importing it via ‘Tools’, ‘Import’, ‘RSS’ in your WP dashboard.
